I’m using SuSe Linux 12 SP2 for my SAP Application, today i’m trying to access my sap server using VNC but was getting “System administrator is not allowed to remote login” error:
It seems, need to allow the remote access of the user root to the display manager, Follow the below procedure for allowing root user to Display manager.
1. edit the file to allow the “ROOT” login to displaymanager:
you will see the DISPLAYMANAGER_ROOT_LOGIN_LOCAL is “no”, modify it to “yes”.
Save the file and try to access the system using VNC, it will work.
